GO AWAY!

Aren't pushy people on the phone just the pits?
Was rung up last week by odious little man who demanded money from us for an invoice supposedly confirmed, by phone, a month or so before. The invoice was for an advert, with money going towards a charity. We had already done one advert in the summer, and were SO not up for yet another one. I explained to him, very nicely, that we were a tiny little pre-school, and not really up for forking out another £600 when we needed every penny for the children. I was sure that he understood, blah, blah,blah.
He didn't.
At all.
He started to get rather unpleasant, and told me that there was a 'recording of the confirmation', and invited me to listen to it.
Which I did.
And could hear myself, (cor, I didn't 'alf sound posh and all) saying Yes to this, and Yes to that, and then explaining that I would be delighted to give the money but not now... and then being talked over by the voice at the other end, before the phone call abruptly ended, and I was left with a £600 bill.
But...!
But...!!
And all of this happening because I am polite to a pushy, aggressive sales person last October.
Believe me, it's hard enough telling these people to naff off when sitting quietly at one's desk, surrounded by paper work and Stuff. But to be surrounded by 20 small children, at our pre-school, one holding my hand, the other needing their nose wiped, it becomes almost impossible to give one's full attention to a full spate of sales technique at the other end of the phone. I kind of zoned out when the pushy sales lady (who rang right in the middle of a morning session at our pre-school) went on and on about how kind we were, and what she wanted, and how she was going to go about doing things for us. But I put the phone down knowing that I hadn't committed to anything. Phew!
Only to get another phone call some time later saying that they were so delighted that I would like another advert (costing £600) and how would I like to pay.
Stutter!
What?!
I was totally taken aback by their engineering of the conversation to make it sound like I HAD confirmed.
The very dull end to this very dull tale is that I am now in the process of trying to prove that I did NOT commit to yet another advert in some poxy publication and that we will NOT be paying out £600 for an advert we don't want.
It is taking up hours of my time, and I am getting more and more annoyed as each phone call, email, letter goes on.
I now have Trading Standards on the case, plus the Federation of Small Businesses.
Feels like bullying. It really does.
Cross your fingers for me, folks.
